Abstract

In the color image processing apparatus according to the invention which reads an image on an original, generates a plural sets of color image components and extract color signal based on the color image components, to eliminate a density fluctuation in such color image processing, the density treatment is performed simultaneously with the color ghost treatment.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. Apparatus for processing a color original image which comprises (1) means for reading a color original image to generate a plurality of color component signals for each pixel of said original image;   (2) means for processing said color component signals to generate a plurality of color image signals wherein each of said color image signals comprises color code data and density data;   (3) means for eliminating a color ghost from said color code data, said color ghost eliminating means storing corrected color code data whereby said color ghost eliminating means outputs corrected color code data in accordance with said color code data, and;   (4) means for correcting said density data in accordance with said corrected color code data.   
     
     
       2. The apparatus of claim 1 wherein said color ghost eliminating means comprises a first and a second ghost eliminating portion. 
     
     
       3. The apparatus of claim 1 wherein said color ghost eliminating means eliminates a color ghost in both horizontal and vertical scanning directions of said apparatus. 
     
     
       4. The apparatus of claim 1 wherein said corrected density data is converted to binary-coded density data. 
     
     
       5. The apparatus of claim 4 wherein said corrected color code data is controlled by said binary-coded density data. 
     
     
       6. The apparatus of claim 1 wherein said corrected density data is converted to tri-state coded density data. 
     
     
       7. The apparatus of claim 6 wherein said corrected color code data is controlled by said tri-state coded density data.
